Firstly great feature packed extension! I have this problem in 2.5.2, so what i did till its fixed, is to get the Session Saver extn from FF, and switch off the Restore Last Session features in TabMixPlus.
They seem to work together with no problems till this is resolved.
I just discovered Tab Mix Plus yesterday when I upgraded to Firefox 1.5. It is just a great extension. I am using v 2.5.2
But I, too, have the problem with "any external link e.g. from an e-mail message, program's online help menu entry etc. " not coming up in Firefox, while the last session does come up.
Has anyone figured out some type of workaround for this? I often click on a link in an email, and now it is just not working unless Firefox is already open.
I'd really appreciate any ideas on this. Thanks.
